generates a list of all possible ntuples of elements from list.

generates a list of all possible tuples whose i^(th) element is from listi.


  • The elements of list are treated as distinct, so that Tuples[list,n] for a list of length k gives output of length kn.
  • The order of elements in Tuples[list,n] is based on the order of elements in list, so that Tuples[{a1,,ak},n] gives {{a_(1),a_(1),...,a_(1)},{a_(1),a_(1),...,a_(2)},...,{a_(k),a_(k),...,a_(k)}}.
  • Tuples[list,{n1,n2,}] generates a list of all possible n_(1)n_(2) arrays of elements in list.
  • The object list need not have head List. The head at each level in the arrays generated by Tuples will be the same as the head of list.
